Boiler Deaerator Working Principle - Boilersinfo

In the Boiler deaerator Working Principle Water is heated close to saturation temperature with a minimum pressure drop and minimum vent. This ensures the best thermal operating efficiency. Deaeration is done by spraying the boiler feed water over multiple layers of trays designed to provide large contact area of the liquid surface to Pegging steam.

Deaerator - Wikipedia

A deaerator is a device that removes oxygen and other dissolved gases from liquids. Deaerators are commonly used to remove dissolved gases in feedwater for steam-generating boilers.Dissolved oxygen in feedwater will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (like rust). ). Dissolved carbon dioxide combines with

Oxygen Deaerator | Boiler Deaerator | MACH Engineering

Vacuum Deaerators: Instead of heating the feedwater to its saturation temperature before stripping away gases, a vacuum deaerator is designed to boil the water at a lower temperature. This is made possible by a vacuum pump, which creates vacuum conditions inside the deaerator and removes oxygen and carbon dioxide by venting out the steam.
